I dont need very deep dives on our lake as the visibility is really poor, but time enough to do a bottom clean is important to me. The 120 volt rig I used was great, but would really like to be able to use it away from the pier. Maybe driving a 120 volt rig with and inverter would be a solution?

Get a used, cheap aluminum scuba tank and a very long regulator hose, and you'll have enough money left over to get scuba certified so you can have your tank filled.
